Claims

[Claims for Utility Model Registration] A parking brake pedal rotatably supported by a pedal bracket from its original position to a depressed position, and operatively connected to the parking brake in order to apply the parking brake in the depressed position; an engaging tooth provided on the pedal along an arc centered on the center of rotation of the pedal; and an engaging tooth attached to the pedal bracket so as to be able to engage and detach from the engaging tooth, and engage with the retaining tooth. a pawl member that prevents the parking brake pedal from returning from a depressed position to an original position; and a forward direction in which the pawl member engages with the retaining tooth and a reverse direction in which the pawl member disengages from the engaging tooth. a biasing device capable of biasing the pole member in the opposite direction and set to a size such that the biasing force in the opposite direction does not cause the pole member to disengage against the engagement force with the engagement teeth; It is supported by the pedal bracket so as to be rotatable about an axis parallel to the rotational axis of the brake pedal, and is operatively connected to the biasing device, and the biasing force of the biasing device is released by pressing the brake pedal to the unlock position. The direction of the biasing force of the biasing device is reversed from the reverse direction to the positive direction by reversing the direction from the forward direction to the reverse direction and returning from the lock release position in conjunction with the return of the parking brake pedal to its original position. A parking brake operation device characterized by including a lock release operation pedal for causing the parking brake to operate.
